Never used Spiderwire, but PowerPro is nothing but the best! Its very tough, very strong, and really hard to break. It is the best braid on the market if you ask me. I run 100lb PowerPro on all my rods and absolutely love them all! I highly recommend it!

I've been using Powerpro for years. Last year, I put Stealth on a couple of reels, and I was impressed by its strength. It was tougher than the Powerpro, in my opinion. Now, after a year of use, the Stealth has gotten pretty ratty, looking worse than even older PP. It discolors faster, which is no big deal, but it also starts to fray a little. Also, the Stealth is a little softer, which seems to cause a few more backlashes. I'm going to stick with Powerpro
